Among the compounds represented by formula (I) above, the following are of particular interest:

3-[3-chloro-4-(phenethyloxy)phenyl]-1.1-dimethylurea,

1-[3-chloro-4-(phenethyloxy)phenyl]-3-methylurea,

3-[3-chloro-4-(β-methylphenethyloxy)phenyl]-1,1-dimethylurea,

3-[3-chloro-4-(α-methylphenethyloxy)phenyl]-1,1-dimethylurea,

1,1-dimethyl-3-[3-nitro-4-(phenethyloxy)phenyl]urea,

3-[3-chloro-4-(phenethyloxy)phenyl]-1,1-diethylurea,

3-[3-chloro-4-(3-phenylpropoxy)phenyl]-1,1-dimethylurea, and

1,1-dimethyl-3-[4-(phenethyloxy)phenyl]urea

The present invention also relates to methods for the preparation of compounds of formula (I) and to methods for the control of monocotyledonous and dicotyledonous plant species using a herbicidally effective amount of a compound of formula (I).

Phenylurea compounds, which may be illustrated schematically by formula (II) ##STR7## wherein R_(a) to R_(c) and X,Y and Z represent various substituents, are known to be herbicides, and a number of patents and published reports attest to their herbitoxic activity. Their use in the agriculture is, however, quite limited and is usually in preemergence applications.

Benzyloxyphenylurea compounds, which may be schematically illustrated by formula (III) below: ##STR8## wherein X,X',Y,Y',Z,Z' and R_(a) and R_(c) represent various substituents, possess postemergence herbicidal activity but lack useful agronomic crop selectivity, nor is their herbicidal activity outstanding.

It has now been found, that the novel para-phenylalkoxy phenylurea compounds of the present invention show not only excellent broadleaf control when applied postemergence but also show an unexpected and useful degree of crop tolerance to wheat, barley, sorghum, corn and rice. Some of these compounds, especially the compounds wherein W is NO₂ also show a useful degree of crop tolerance to cotton and soybeans. Crop selectivity may be further modified by applying these compounds to said crops at different growth stages.

Said compounds also display preemergence herbicidal activity although at higher rates than those needed for postemergence control.

The compounds of formula (I) wherein X is O and A is C₂ -C₈ alkylene may be conveniently prepared by the route shown below: ##STR9## wherein Y,Z,W,R₁,R₂ and R₃ are as hereinabove defined except when Y═OH, NH₂ in which case they are suitably protected, L is selected from --OSO₂ CH₃ or halide. Thus the methanesulfonate ester of the appropriately substituted phenylalkanol or the corresponding phenalkylhalide of formula (IV) is reacted with an ureidophenol of formula (V) in the presence of an organic or inorganic base, preferably potassium t-butoxide, and a solvent such as dimethylformamide in the temperature range of from 20° C. to 90° C. and preferably 60° C. to 80° C., for a period of time sufficient to essentially complete the reaction.

Formula (I) compounds, in which the alkylene chain (A) is substituted, may be prepared as follows: ##STR10## wherein Y,Z,W and R₁ to R₃ are as hereinabove defined and n is an integer of from 1 to 7. Next, the thus obtained compound of formula (VII) is hydrolyzed to yield the corresponding benzoylalkoxyphenylurea as illustrated below: ##STR11##

In the above depicted sequence the appropriately substituted 1,3-dioxolane of formula (VI) is reacted with an ureidophenol of formula (V) in the presence of an organic or inorganic base, preferably potassium t-butoxide and a solvent such as DMF in the temperature range of from 20° C. to 90° C., preferably 50° to 80° C. for a period of time sufficient to essentially complete the reaction. The thus obtained urea of formula (VII) is then hydrolyzed with an aqueous acid, such as hydrochloric acid to yield a benzoylalkoxyphenylurea of formula (VIII). The benzoylalkoxyphenylurea compounds of formula (VIII) may be reduced by known methods to the corresponding alcohols which are valuable intermediates for the preparation of formula (I) compounds wherein the alkylene chain (A) is substituted as defined above. Such a preparation may be schematically illustrated as follows: ##STR12##

An alternate route leading to formula (I) compounds comprises reacting an isocyanate or isothiocyanate of formula (XII) ##STR13## with an equimolar or excess amount of an amine of formula ##STR14## to yield the desired formula (I) compound: ##STR15## wherein R₁ is hydrogen and X,Y,Z,W,R₂ and R₃ are as hereinabove defined.

Similarly, the appropriate aniline of formula (XIII) ##STR16## may be reacted with an isocyanate or isothiocyanate of formula R₃ --N═C═Q to yield a formula (I) compound of structure ##STR17## wherein R₁ and R₂ are both hydrogen, and R₃ is an hereinabove defined.

Conveniently, the methanesulfonate ester of an appropriately substituted phenylaklanol of formula (IV) and an appropriately substituted ureidophenol of formula (V) may be reacted in a two phase system using a phase transfer catalyst such as benzyl tributylammonium chloride and the like, to obtain the desired herbicide of formula (I): ##STR18##

The above described preparations are further illustrated in the experimental detail appended hereto.

Formula (I) compounds, wherein X is SO or SO₂ are prepared by a slightly different route, as shown below: ##STR19## wherein A,Q,Y,Z,R₂ and R₃ are as defined above except that Y cannot be NO₂ and m is an integer of 1 or 2.

By the above depicted route, p-nitrothiophenol of formula (XIV) is reacted with the appropriately substituted methanesulfonate ester of a phenylalkanol or the corresponding phenalkyl halide of formula (IV) in the presence of an inorganic or organic base, preferably potassium t-butoxide and a solvent, such as DMF, in the temperature range of from 20° C. to 90° C., and preferably 60° C. to 80° C. for a period of time sufficient to essentially complete the reaction. The nitro compound (XV) obtained by the above reaction is then reduced with sulfurated sodium borohydride to afford the amine of formula (XVI). This amine (XVI) is then reacted with dialkylcarbamoylchloride or the appropriate isocyanate to yield the corresponding urea (XVII). Oxidation of this compound (XVII) affords the desired urea (I).

As stated above, formula (I) compounds of the present invention show excellent postemergence control of broadleaf weeds coupled with crop selectivity in the presence of sorghum, rice and wheat.

Said compounds also display preemergence herbicidal activity coupled with selectivety, however at somewhat higher rates than needed for postemergence control.

Surprisingly, we also find that the compounds of the invention are highly effective as fungicides useful in the treatment of agronomic crops.

In practice, the active compounds are generally formulated as dusts, dust concentrates, wettable powders, emulsion concentrates, flowable concentrates and the like.

Dusts can be prepared by grinding about 1% to 15% by weight of active compound with about 99% to 85% by weight of an inert diluent such as attaclay, diatomaceous earth, kaolin, pumice, talc and the like.

Dust concentrates are made in a similar fashion expecting that percent by weight of active ingredient is increased to about 16% to 75% of the composition.

Wettable powders are prepared in the same manner as dust concentrates, but usually contain, in addition to the active ingredient and solid diluent, from about 1% to 5% by weight of a wetting agent such as sodium isopropylnaphthalene sulfonate or the sodium salt of a sulfonated naphthalene formaldehyde condensate, and from about 1% to 5% by weight of a dispersing agent such as hydroxyethyl cellulose. A typical formulation would be 50% by weight of active ingredient, 2% of dispersing agent, 5% of wetting agent and 43% attapulgite.

Emulsion concentrates are prepared by dissolving 15% to 70% by weight of the compound in 85% to 30% by weight of a solvent such as benzene, toluene, xylene, kerosene, 2-methoxy ethanol, propylene glycol, diethylene glycol, diethylene glycol monomethyl ester, formamide, methylformamide and the like, and mixtures thereof. Advantageously, surfactants such as polyoxyethylated vegetable oil or an alkyl phenoxy polyoxyethylene ethanol are also incorporated in amounts of 1% to 5% by weight of said concentrate.

In using wettable powders, emulsion concentrates, flowable concentrates and the like, the formulated material is generally dispersed in water and applied at a rate of from 0.03 kg per hectare to about 2 kg per hectare to the plants or to the soil containing the seeds of said plants.

The invention is further illustrated by the following examples which are not to be taken as being limitative thereof.

EXAMPLE 1 General Method for the Preparation of Phenylalkoxyphenyl dimethylurea compounds [Method A]

The appropriate ureidophenol (0.03 mol), dimethylformamide (DMF;200 ml) and potassium t-butoxide (0.03 mol) are mixed and stirred at room temperature under a nitrogen atmosphere for one hour. Next, the appropriate methanesulfonate ester (0.03 mol) is added and the reaction mixture heated at 80° C. from 2 to 18 hours. The solution is then cooled down and the DMF removed under vacuum. The residue is dissolved in methylene chloride and water (made basic with a few drops of 1 N sodium hydroxide). The organic layer is washed with water and filtered through a 5 cm thick layer of neutral alumina. The alumina layer is washed with acetonitrile, filtrate and washings are combined and evaporated to afford the desired urea. The product may be further purified by recrystallization from the appropriate solvent.

The compounds made by this procedure are listed in Table I below.

EXAMPLE 2 Preparation of 3-[3-chloro-4-(phenethyloxy)phenyl]-1,1-dimethylurea [Method B]

Dimethylamine (7.0 ml; 0.068 mol) is added at room temperature and under a nitrogen atmosphere to a 0.11 M solution of 3-chloro-4-(phenethyloxy) phenylisocyanate in toluene (145 ml, 0.016 mol). The reaction is exothermic and the temperature of the mixture rises to 40° C. The solution is stirred overnight and then treated with 10% aqueous sodium hydroxide (50 ml). The organic layer is separated and washed in succession with 50 ml portions of 10% aqueous sodium hydroxide, water 3 N hydrochloric acid (twice), water and brine. The solution is dried over potassium carbonate and then concentrated under vacuum to an amber oil. The oil is dissolved in hot hexaneethyl acetate mixture with the formation of a precipitate. The mixture is cooled and filtered to afford 4.27 (0.0123 mol; 77%) of title product, m.p. 89°-90° C.

EXAMPLE 22 Preparation of 2-(3-chloropropyl)-2-phenyl-1,3-dioxolane

A mixture of γ-chlorobutyrophenone (33.2 g; 0.182 mol), ethylene glycol (20.3 ml; 0.363 mol), p-toluenesulfonic acid (a pinch) and toluene (300 ml) is heated at reflux for 40 hours, and the water formed in the reaction is azeotroped off. After 20 hours, more ethylene glycol (20.3 ml; 0.363 mol) is added. On completion of the reaction the mixture is extracted with saturated aqueous sodium bicarbonate solution (300 ml), the organic layer is washed with 1 N sodium hydroxide solution and then with water, and is evaporated to afford 37.0 g of a cream colored solid, m.p. 54°-55.5° C.

EXAMPLE 23 Preparation of 3-{3-chloro-4-(2-phenyl-1,3-dioxolan-2-yl)propoxy)phenyl}-1,1-dimethylurea

A mixture of 3-(3-chloro-4-hydroxyphenyl)-1,1-dimethylurea (6.44 g; 0.03 mol), potassium-t-butoxide (3.37 g; 0.03 mol) and DMF (200 ml) is stirred for 30 minutes, then 2-(3-chloropropyl)-2-phenyl-1,3-dioxolane (6.8 g; 0.03 mol) is added and the reaction mixture stirred for 5 days at 50° C. The reaction mixture is then poured into brine and extracted with methylene chloride. The organic layer is washed with water and filtered through a 5 cm deep bed of neutral alumina. The alumina bed is washed with acetonitrile, filtrate and washings are combined and evaporated to afford 11.42 g of product, a red-brown oil, which slowly crystallizes. Recrystallization from a toluene-hexane mixture (200 ml) yields 6.2 g of bronze colored needles, m.p. 127.5°-130° C.

EXAMPLE 24 Preparation of 3-[4-(3-benzoylpropoxy)-3-chlorophenyl]-1,1-dimethylurea

A mixture of 3-{3-chloro-4-[3-(2-phenyl-1,3-dioxolan-2-yl)propoxy]phenyl}-1,1-dimethylurea (2.03 g; 0.005 mol), tetrahydrofuran (10 ml) and 10% aqueous hydrochloric acid (2 ml) is stirred overnight. The reaction mixture is poured into brine (100 ml) and extracted with methylene chloride. The organic layer is washed with water, dried and evaporated to afford the product: 1.69 g of an off-white solid. Recrystallization from a toluene-hexane mixture (50 ml) yields 1.33 g of cream colored needles, m.p. 129°-130° C.

EXAMPLE 25 Postemergence Herbicidal Activity

The postemergence herbicidal activity of the compounds of the present invention is demonstrated by the following tests, wherein a variety of monocotyledonous, and dicotyledonous plants are treated with test compounds dispersed in aqueous acetone mixtures. In the tests, seedling plants are grown in separate cups for about 2 weeks. The test compounds are dispersed in 50/50 acetone/water mixtures containing 0.5% TWEEN®20, polyoxyethylene sorbitan monolaurate surfactant of Atlas Chemical Industries, in sufficient quantity to provide the equivalent of about 0.063 kg to 2.0 kg per hectare of active compound when applied to the plants through a spray nozzle operating at 2.81 kg/cm² pressure for a predetermined time. After spraying, the plants are placed on greenhouse benches and are cared for in the usual manner, commensurate with conventional greenhouse practices. Two weeks after treatment, the seedling plants are examined and rated according to the rating system provided below. The data obtained are reported in Table III below. The data in said table have been obtained either by a single trial or by replicating a trial two or more times, in which case the data are reported as averages.

EXAMPLE 26 Preemergence Herbicidal Activity

The preemergence herbicidal activity of the compounds of the present invention is exemplified by the following tests in which the seeds or propagating organs of a varity of monocotyledonous and dicotyledonous plants are separately mixed with potting soil and planted on top of approximately 2.5 cm of soil in separate cups. After planting, the cups are sprayed with selected aqueous/acetone solution containing test compound in sufficient quantity to provide the equivalence of about 0.07 kg to 2.0 kg per hectare of test compound per cup. The treated cups are then placed on greenhouse benches, watered and cared for in accordance with conventional greenhouse procedures. Three to five weeks after treatment, the tests are terminated and each cup is examined and rated according to the rating system set forth in Example 25. The data obtained are reported in Table IV below.

The rates displayed in Table IV below are the averages of two or more replicates.
